I was wondering if the lcd1602 with i2c module is usable with a 3.3v PIC? I would like to use it with an IOIO

Hi, that LCD only works at 5V, you would need to use an I2C level converter, to convert your uControllers 3.3V I2C message to 5V I2C message. You will also need an external voltage supply.

We will be selling the I2C level converter probably by next week.
